IMPROVEMENT IN BALE-TIES.

Specification forming part of Letters Patent No. 198,976, dated January 8,1878; application. filed December 19,1877. 7

To all whom it may concern:

Be it known that I, SAMUEL H. GILMAN, of the city of New Orleans, in the parish of Orleans and State of Louisiana, have invented a new and useful Improvement in Bale-Ties, which .improvement is fully set forth in the following specification and accompanying drawings, in which latter- Figure 1 is a perspective view of one of my improved bale-ties as it appears when locked.

Fig.2 is a longitudinal vertical central section of the same. Figs. 3 and 4 are perspective views of two interlockingjaws, which constitute the tie-plates. 7

My invention consists of certain constructions, combinations, and arrangements of parts, hereinafter fully described and specifically claimed, whereby a self-locking bandtie for bales is produced, which has a very powerful double gripe and can with great ease be repeatedly locked and unlocked.

In the drawings, A represents an oblong frame, consisting of two parallel curved side pieces, a, and two parallel connecting-pieces, a 0. between which latter the side pieces a are provided with open fulcrum-bearings a at a greater distance from 0, than a). B represents a clamp-plate of suitable width so as to fit into the frame A, and having two trunnions, b, which fit the bearings a of the said frame. Near the said trunnions the plate B is provided with a groove, N, which is directly opposite the connection a when the tie is put together. This groove forms a concave seat for the bar a to seat itself in.

At the opposite end the plate B is forked, as at 12 and the so-formed two arms I) are finally united by a transverse connection, b being sufficient to admit that part of the frame A which has the connection a constructed upon it.

By this construction, in connection with the tension of the band, a compound-lever tie of great holding capabilities is produced, whereby the leverage-strain of the band, as at 00, upon the tie at one of its ends, as at a, causes the tie at the other end, as at a to indent and firmly bite upon the band, as at :0 with an increased leverage-power.

Operation: The two parts A and B of the bale-tie are united byinserting one end of the plate B between the frame A, so that the trunnions 'b enter into the bearings a and the cross-bar a occupies a position below the groove 12 as shown in Figs. 1 and 2.

The band as is next so bent around the connecting-bar a that in passing to and from it it also passes beneath the connection If of the clamp-plate B. p

The band a" is now ready to be pulled tight around the bale, and after this is done the free end so of the band is placed between the connection a and the grooved portion 11 The tightening hold on the band is now released, whereupon the strain of the bale causes the band to pull the connections a and 1) toward each other, thereby forcing the connection a and the grooved portion b together with great power, as their leverage is only a small fraction of the leverage of the connections a and W,

The aforesaid free end 90 which is flat when introduced now bent and partly forced into the groove b and thereby receives a transverse indentation, :0 as shown in Fig. 2, which, inconjunotion with the great clamping force exerted upon it, constitutes a bite upon the part 00 of the band SllffiGlGlllJ to resist any strain which the bale exer s to withdraw the end 00 from the tie.

To open the tie, it is only necessary to insert a small bar or other suitable instrument horizontally between the arms b and the curved side pieces a and pry them apart, whereupon the bite upon the band at x will be released.

Having described myinvention, whatl claim 1s-- 1. The combination of the bale-tie pieces A and B, provided with a fulcrum, b, and connections a 11 clamping-groove b, and con nection 00, substantially as and for the purpose set forth.

2. A compound levergriping cotton -bale tie, having two jaws, which are connected together, and are provided, respectively, with cross-bars, as at a and b said tie having one end of the cotton-bale band passed around its bar a and under its bar b ,'and the other end of said band being griped between the of the band :20, into the tie, is

jaws of the tie, substantially as and for the purpose described.
